Built on top of a tapered brick platform, this building had a solid brick foundation that extended for 50 meters east west and 27 meters north south. The foundation was divided into 27 square and rectangular blocks by narrow passageways, two running east west and eight running north south. A section of the northern foundation had hollow sockets for wooden beams used to support a stairway or wooden structure. Later wells and walls are seen in the foreground.
